Err that's perfectly normal. Linux does buffering/caching meaning that it will keep all files/libraries it has opened/read will remain cached in the memory until the memory is needed otherwise.
Try running 'free' (without quotes) you'll see something like this: total used free shared buffers cached Mem: 126980 124180 2800 0 11120 59596 -/+ buffers/cache: 53464 73516 Swap: 498004 38044 459960 You'll see total, used, free, shared, buffers, cached. As you can see with me I have 126,9MB (the memory that the kernel uses isn't counted) from which 124,1 is used and 2,8 is free, however 11,1 from that is buffer and 59,5!!!!! is cached, as you will notice you have a bar called -/+ buffers/cache now if you'll look there you'll see that the actual memory needed is 53,4MB and that 73,5 is still free if you don't count the cache and buffers.
